Improvement in harvester-cutters



UNITED STATES ATENT Trrcn.

. IMPROVEMENT lN HARVESTER-CUTTERS.

Specification forming part of Letters Patent No. 12,327, dated January 30, 1855.

To all whom it may concern.- l

Be it known that I, DAVID RUSSELL, o Drewersburg, in the county ot' Franklin and State ot' Indiana, have invented anew and useful Improvement in 'Gutters for Harvesters; and I do hereby declare that the followingis a full and exact description thereof, reference being had tothe accompanying drawings, making a part ot' this specification.

Figure l is a top View ofthe Wheels, chains, and cutters with the top ofthe case removed. Fig. 2 is an edge view of the case, showing the driving-pulleys d d below.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I construct my improved cutters out of any of the ordinary materials used for such purpose, and the endless chain may be either a chain, strap, or rope, or all combined.

Letters a a a a, Fig. l, are the cutters. Letters b b, Fig. 1, are the Wheels.

Letters c c, Figs. l and 2, are the chains.

Letters d d, Fig. 2, are the pulleys.

The cutters a a a a are let into the chains on the inner sides by dovetailing them in and fastening them by screws, making the chains a smooth surface after the cutters are let in. rlhe driving-pulleys d d are attached to the shaft passing through the cog-wheels b b, over which the endless chains play, and as they revolve reverse] y to each other the knives pass over each other in the form of shears, cutting all the grain caught in their grasp, and the rapidity with which they move is constantlycutting the grain as fast as themachineis moved along. The cutters are put' at a given distance of eight or ten inches from each-other on each chain.

Having thus fully described the nature and operation of my improvement, What I claim as my invention, and desire to secure by Letters Patent, is

The combinatiouof cutters with an endless chain or chains operatingas described, and for the purposes set forth in my snecitication.

' DAVID RUSSELL.
